The paper develops an algorithm to transform symmetric attractor models into functionally equivalent heterogeneous models, showing hidden symmetries in fly connectomes support ring attractor dynamics.

The paper shows that small neural networks with as few as 4 neurons can accurately integrate angular velocity for spatial navigation, challenging the need for large ring attractor networks.

This paper describes a neural circuit framework in Drosophila that enables rapid behavioral adaptation through head direction and goal representations during navigation.

The paper identifies neurons in Drosophila that encode rotational velocity using motor and visual signals, updating the fly's neural compass through a mechanism that prioritizes motor information when signals are congruent.

The paper investigates CA3 intracellular dynamics during awake ripples in mice, finding that inhibition in CA3 is critical for ripple generation, while DG and CA1 show depolarization transients before ripples.

The paper presents the first complete connectome of the Drosophila central complex, revealing network motifs that support flexible navigation and context-dependent action selection.

Structure-guided mutagenesis of GCaMP6 plus neuron-based screening yields a jGCaMP7 family, each variant tuned to a different regime: single spikes, neurites and neuropil, or population imaging.
